thats why i had to asked on here , i am sorry if you thought it was a stupid question . i am trying to learn everything possible about cameras/photography.
and this is hands down the best site i have found to help me learn everything i need to know.

whats it gonna be a human style of an eye that all you do is have to looke at something and it does everything for you and it would be a perfect pic just like the human eye sees , no dead or hot pixels to worry about , no dust or vibration

I suspect we'll still be complaining about noise levels on the latest 72 Megapixel compacts!

Seriously though, it is interesting that DSLRs - surely some of the hottest cameras around right now - are essentially unchanged externally from SLRs of several decades back. It seemed the designers came up with a classic shape which still works well today - albeit with significantly more sophisticated innards...
